Small nit pick - ‘ferrous’ just means it has iron in it and does not guarantee infinite cycle life. Cast iron or pig iron, for example, have a cycle limit.
For some reason, the inclusion of Carbon with Iron is what makes a material with infinite cycle life under a certain load, so Steels are generally the only materials with infinite cycle life at low cycle loads.
